During the Devonian the area currently delimited by the Murzuq Basin in SW Libya, was part of a slowly subsiding, extensive, low angle, platform cratonic margin, situated on northern Gondwana. Phases of tectonism occurred ...

Darnel (Lolium temulentum L.), the subject of this review, is botanically and culturally significant because of its evolutionary origin as a mimic weed of cereals and its reputation as a source of potent psychoactive toxins. ...

Autonomous robot road following has been widely investigated since the early 1980s and, whilst much progress has been shown, there is still no system which displays 100% generality across all types of problem. This work ...

An overview of the application of evolutionary computation to fuzzy knowledge discovery is presented. This is set in one of two contexts: overcoming the knowledge acquisition bottleneck in the development of intelligent ...

A system to coordinate the movement of a group of unmanned aerial vehicles that provide a network backbone over mobile ground-based vehicles with communication needs is presented. Using evolutionary algorithms, the system ...

Mammographic risk analysis is an important and challenging issue in modern medical science; research and development in this area has recently attracted much attention. Many efforts have been devoted to achieving a higher ...

Background Evolutionary processes in gene regulatory regions are major determinants of organismal evolution, but exceptionally challenging to study. We explored the possibilities of evolutionary analysis of phylogenetic ...

Background Understanding the evolution of cultivated barley is important for two reasons. First, the evolutionary relationships between different landraces might provide information on the spread and subsequent development ...

Ecologists have had limited success in understanding which introduced species may become invasive. An evolutionary model is used to investigate which traits are associated with invasiveness. Translocation experiments were ...

Different mutation operators have been developed in evolutionary programming. However, each operator may only be efficient in certain specific fitness landscapes only. In order to combine the advantages of different ...

Evolutionary Programming (EP) has been modified in various ways. In particular, modifications of the mutation operator have been proved to be capable of significantly improving the performance of EP. However, while each ...

For many years, researchers in the field of mobile robotics have been investigating the use of genetic and evolutionary computation (GEC) to aid the development of mobile robot controllers. Alongside the fundamental choices ...

This article describes a simulation model in which artificial evolution is used to design homogeneous control structures and adaptive communication protocols for a group of three autonomous simulated robots. The agents are ...

We use a genetic algorithm to evolve neural models of path integration, with particular emphasis on reproducing the homing behaviour of Cataglyphis fortis ants. This is done within the context of a complete model system, ...

This research work illustrates an approach to the design of controllers for self-assembling robots in which the self-assembly is initiated and regulated by perceptual cues that are brought forth by the physical robots ...
